Electrically connecting device for superconducting wires

An electrically connecting device comprising:

• a linking part defining an internal channel that opens onto the exterior of the linking part, said internal channel being able to receive two end segments of two superconducting wires;
• and
• an aperture in the external jacket of the linking part, said aperture being in communication with said internal channel in order to allow a brazing material in liquid form to be introduced into said internal channel around the two end segments of the two superconducting wires;
• characterized in that the linking part comprises a central elongate body, the internal channel extending in a straight line between a first open end and a second open end of the linking part, said ends being located on either side of the central elongate body,
• in that said internal channel is configured so that the two end segments of two superconducting wires lie parallel and in contact with each other in the internal channel over said segment of common length, and in that the internal channel has in cross section the shape of an eight.
